Grey Armor

Grey Armor Model I, Mark I: Tony's first armor was designed as a escape plan and also to keep his heart beating. It was luck that it even worked. It was made from a 3D knitted metal shell that was actually made from ordinary iron. It's most important use was the built in pacemaker that kept Stark's heart beating. It was run buy tiny electronic transistors. The exoskeleton amplified his strength to super human levels. His actual movement was created by DC armature motors. An odd feature was that the suit could recharge in ordinary wall sockets which was a great help because the first suit was a energy hog. He was equip with air pressure boots capable of short flight. He was also equip with gauntlet suction cups and even a small buzz saw. (mounted on his index finger)   Armaments: Chest mounted proton beam emitor, early repulsors
